The tie-up cords for the treadles have already
been cut to the correct lengths.
Lead a cord around the lam and insert one end
into the loop at the other end, the one next to
the loop where the cord has been cut.
Pull the cord, so that the loop you made
around the lam is tight.
Hook the other end of the cord to the
corresponding screw head of the treadle.
Tie-up the treadles for the weaving project you
planned, or tie at least each lam to a treadle.
A spring for each shaft is located at the top of
the David. These springs pull up the shafts by
cords that run over a wooden disc.
A locking pin at the top right of the loom
blocks the moving action of springs, discs,
shafts, lams and treadles.
This locking pin is inserted into holes in the
front and back rail and into holes in the
wooden discs.
Remove the locking pin. It helps when you
push the shafts a bit downwards.
Look at the situation now: The shafts are pulled upwards by the springs. Because the lams are
connected to the shafts and the treadles are connected to the lams, treadles and lams are pulled
up as well. The upward movement of the shafts is blocked by the treadles that hit the bottom rail.
So the level of the shafts is determined by the distance between treadles and shafts and not
by the lengths of the disc cords from which the shafts hang. If necessary, the level of the
shafts has to be adjusted by adjusting the lengths of the slanting cords that connect the
shafts to the lams.
When you shorten these cords by one loop at the hooks of the lower shaft bar, the shaft will come
down about 2 cm (3/4”). In most cases, that will be too much. For finer adjustment, use the plastic
pegs to adjust the lengths of these cords. Every loop you thread the peg through, will shorten the
cord by about 1.5 mm (1/16”).
